abstract = {Let $\lbrace \beta (n)\rbrace ^\{\infty \}_\{n=0\}$ be a sequence of positive numbers and $1 \le p < \infty $. We consider the space $H^\{p\}(\beta )$ of all power series $f(z)=\sum ^\{\infty \}_\{n=0\}\hat\{f\}(n)z^\{n\}$ such that $\sum ^\{\infty \}_\{n=0\}|\hat\{f\}(n)|^\{p\}\beta (n)^\{p\} < \infty $. We investigate strict cyclicity of $H^\{\infty \}_\{p\}(\beta )$, the weakly closed algebra generated by the operator of multiplication by $z$ acting on $H^\{p\}(\beta )$, and determine the maximal ideal space, the dual space and the reflexivity of the algebra $H^\{\infty \}_\{p\}(\beta )$. We also give a necessary condition for a composition operator to be bounded on $H^\{p\}(\beta )$ when $H^\{\infty \}_\{p\}(\beta )$ is strictly cyclic.},

AB - Let $\lbrace \beta (n)\rbrace ^{\infty }_{n=0}$ be a sequence of positive numbers and $1 \le p < \infty $. We consider the space $H^{p}(\beta )$ of all power series $f(z)=\sum ^{\infty }_{n=0}\hat{f}(n)z^{n}$ such that $\sum ^{\infty }_{n=0}|\hat{f}(n)|^{p}\beta (n)^{p} < \infty $. We investigate strict cyclicity of $H^{\infty }_{p}(\beta )$, the weakly closed algebra generated by the operator of multiplication by $z$ acting on $H^{p}(\beta )$, and determine the maximal ideal space, the dual space and the reflexivity of the algebra $H^{\infty }_{p}(\beta )$. We also give a necessary condition for a composition operator to be bounded on $H^{p}(\beta )$ when $H^{\infty }_{p}(\beta )$ is strictly cyclic.
